Quantum Computing Jobs

• Oxford
• Senior

Keeps a fleet of quantum computers running by root-causing mechanical, vacuum, cryogenic and thermal faults on live systems and prioritising fixes by uptime impact. Designs, prototypes and tests solutions to recurring failures, then writes assembly and upgrade instructions to roll changes into existing fleets, maintaining PLM records and ECRs so fixes carry into future builds.

SolidWorks

• Oxford
• Hybrid
• Mid-level

Build and operate the software controlling the supporting hardware of trapped-ion quantum computers, from cryogenic compressors to lasers, wavemeters and sensors. You'll own device controllers end to end — API design, implementation, fleet rollout and operational health — working in a Rust codebase with hardware protocols like SCPI, serial, TCP/IP and USB alongside software, systems and quantum science teams.

• Berkeley, United States
• Hybrid
• US$180,000 – US$230,000 pa
• Mid-level

Owns end-to-end deployment of quantum computing systems both on-premises at customer and partner sites and on the cloud platform, acting as the technical point of contact from site requirements through installation, validation and handoff. Combines DevOps work — Kubernetes, AWS, Terraform, CI/CD, observability — with on-site commissioning, SRE support and root-cause analysis, with international travel and on-call during installations.

• Hybrid
• US$190,000 – US$240,000 pa
• Senior

Hands-on role owning networking and physical infrastructure across Berkeley labs and a Fremont fabrication facility, including routing, racking, cabling, switches, firewalls and storage, while also supporting AWS cloud environments and infrastructure-as-code. The engineer flexes between data center work and cloud/DevOps tasks such as Terraform, Kubernetes and CI/CD, building new infrastructure as lab and fab space expands.
